Remember these rifles are mostly geared towards non(or beginner) double rifle aficionados. It is my personal guess that a 45-70 would be a top seller. Guys like me would eat it up, cheap and easy to buy brass bullets and factory ammo to get you started.

As far as simply rechambering to something with more power and shooting I don't know if it would work easily anyhow. There is very limited amount you can do with that jack screw. The floater bbl must always "chase" the fixed bbl when regulating. That means as recoil increases the whole gun will shoot more and more to the left. The rifle I had all ready had the rear sight all the way to the right (gun shot left) there was very little adjustment left. I am left handed, having the rear sight to the right was not a problem, a right hander would have had issues. A scope may solve that problem I guess??? I got the impression that the fixed bbl was not "angled" inwards enough, something I hope they addressed.
